Alstroemeria plant named ‘Zaprilet’

ABSTRACT

A new and distinct cultivar of  Alstroemeria  plant named ‘Zaprilet’, characterized by its upright and somewhat outwardly spreading plant habit; vigorous growth habit; red-colored flowers; and good garden performance.

Botanical designation: Alstroemeria hybrida.

Cultivar denomination: ‘Zaprilet’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Alstroemeria plant, botanically known as Alstroemeria hybrida, commercially used as a potted Alstroemeria, and hereinafter referred to by the name ‘Zaprilet’.

The new Alstroemeria is a naturally-occurring whole plant mutation of the Alstroemeria hybrida cultivar Staprioxa, disclosed in U.S. Plant Pat. No. 14,075. The cultivar Zaprilet was discovered and selected by the Inventor as a single plant within a population of plants of the cultivar Staprioxa in a controlled environment in Rijsenhout, The Netherlands in May, 2002.

Asexual reproduction of the new Alstroemeria by rhizome divisions in a controlled environment in Rijsenhout, The Netherlands since September, 2002, has shown that the unique features of this new Alstroemeria are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

The cultivar Zaprilet has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment and cultural practices such as temperature and light intensity, without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Zaprilet’. These characteristics in combination distinguish ‘Zaprilet’ as a new and distinct cultivar of Alstroemeria:

-   -   1. Upright and somewhat outwardly spreading plant habit.     -   2. Vigorous growth habit.     -   3. Dark red-colored flowers.     -   4. Good garden performance.

Plants of the new Alstroemeria can be compared to plants of the parent, the cultivar Staprioxa. Plants of the new Alstroemeria differ primarily from plants of the cultivar Staprioxa in flower color as plants of the new Alstroemeria have darker red-colored flowers than plants of the cultivar Staprioxa. In addition, outer perianth segments of plants of the new Alstroemeria have more stripes than outer perianth segments of plants of the cultivar Staprioxa.

Plants of the new Alstroemeria can be compared to plants of the Alstroemeria hybrida cultivar Staprilene, disclosed in U.S. Plant Pat. No. 11,683. In side-by-side comparisons conducted in Rijsenhout, The Netherlands, plants of the new Alstroemeria differed from plants of the cultivar Staprilene in the following characteristics:

-   -   1. Plants of the new Alstroemeria were not as broad as plants of         the cultivar Staprilene.     -   2. Plants of the new Alstroemeria had shorter leaves than plants         of the cultivar Staprilene.     -   3. Plants of the new Alstroemeria had smaller flowers than         plants of the cultivar Staprilene.     -   4. Plants of the new Alstroemeria and the cultivar Staprilene         differed in flower color as plants of the cultivar Staprilene         had pale yellow and white-colored flowers.

BRIEF DESCRIPTION OF THE PHOTOGRAPH

The accompanying colored photograph illustrates the overall appearance of the new Alstroemeria, showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Colors in the photograph may differ slightly from the color values cited in the detailed botanical description which accurately describe the colors of the new Alstroemeria. The photograph comprises a side perspective view of a typical flowering plant of ‘Zaprilet’ grown in a container.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photograph and following observations and measurements describe plants of the new Alstroemeria grown in Rijsenhout, The Netherlands during the winter in a glass-covered greenhouse in 14-cm containers. During the production of the plants, day temperatures ranged from 15° C. to 25° C., night temperatures ranged from 10° C. to 15° C. and light levels averaged 5,000 lux. Plants used for the photograph and description were about four months from planting.
